【摘要】 在基于转子磁场定向的旋转坐标系下,建立了不带磁通闭环的只带转速闭环的交流异步电机转差频率矢量控制系统仿真模型,实现了交流异步电机的解耦控制.转速闭环采用带限幅的PI调节器,主电路采用电流滞环控制PWM逆变器.仿真结果表明,转差频率矢量控制系统具有良好的动静态性能.更多还原

【Abstract】 Based on the rotor flux-oriented coordinate,simulation model of AC motor control system without flux closed-loop is established and its decoupling control is realized.The PI controller with limited amplitude is adopted in speed loop.Hysteretic-current-loop PWM invertor is its main circuit.A promising result has been testified of this system by the simulation result.更多还原
